81568-08-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81568-08-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,6 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 81568-08:
(7*8)+(6*1)+(5*5)+(4*6)+(3*8)+(2*0)+(1*8)=143
143 % 10 = 3
So 81568-08-3 is a valid CAS Registry Number.

, p. 179 - 182 (2007/10/02)
It is shown that in the reaction of 2-vinylpyridinium quaternary salts with methylammonium sulfite under isomerization recyclization conditions a water molecule adds initially to the double bond of the vinyl substituents, after which the resulting carbino
